Description

  The present invention relates to a concealed postcard that can be sent in a concealed state in order to prevent the information entered in the postcard from being stolen by a third party before the postcard sent to the recipient is delivered. This is related to a concealed postcard that can be clearly confirmed if the fact is opened and seen by the three parties.

  Conventionally, various concealed postcards that have been devised so that the contents described in the mailed postcards cannot be stolen by a third party before being delivered to the recipient have been developed and used. As for these concealment postcards, for example, a two-fold postcard composed of an upper piece serving as a concealment piece through a perforation for folding using a folding sheet approximately twice the size of a postcard, and a lower piece serving as a postcard body piece for entering information. In this case, after the recipient has received the postcard, the recipient has received a postcard that has been concealed by adhering a piece of concealment paper to the postcard body piece, and the recipient can see through the concealment piece and the layers can be peeled off. An information concealment postcard preparation sheet provided with a transparent sheet having a transparent adhesive on both sides of the bonding material is known (see, for example, Patent Document 1).

  The information concealment postcard preparation sheet disclosed in Patent Document 1 is composed of a release sheet and a transparent sheet having a transparent adhesive layer on both sides. When the contents written on the postcard preparation sheet are concealed, It is necessary to peel the release paper provided on the uppermost layer to expose the pressure-sensitive adhesive layer provided on the transparent sheet. However, in such a conventional postcard preparation paper, when the release paper is peeled off, there is a possibility that the paper is accidentally peeled off together with the release paper together with the transparent sheet. In this case, once the transparent sheet is peeled off, the postcard preparation sheet cannot be used again, and a new postcard preparation sheet must be used. Therefore, when the user peels off the release paper provided at the uppermost position in the release paper or the postcard-preparing paper having a transparent sheet having an adhesive layer or a release agent layer, the release paper is used. A postcard-preparing paper with an adhesive layer that directly adheres a part of the transparent sheet and a part of the concealing paper piece is proposed so that the transparent sheet provided in the lower layer of the paper is not peeled off at the same time. (For example, refer to Patent Document 2).

The technique disclosed in Patent Document 1 is such that when the recipient of the postcard is opened in a spread state, the interlayer of the transparent sheet is peeled off between the layers of the joining material that is polymerized so as to be peelable. In the technique, the peeling is performed between the release agent layer and the adhesive layer provided on the lower side of the transparent sheet. However, in any technique, once the recipient opens the paper in a spread state, each layer is not re-adhered, but since there is no evidence of opening, it is seen by a third party. There is a risk of mischief of re-adhesion and restoration.
